She is making too much money at this point to consider running IMO, and the other reason she won't IMO go in 2012 is she wants to probably spend more time in the public eye converting all the regular people to her side.
She is likely to be the next potential President after the one elected in 2012 IMO. By that time her own appearances over the years will make her less smear proof and the Press will have then little or no influence her election.
All my opinion, but I'd be shocked if she ran in 2012.
Remember she said Obama has no cojones about border security? She has more to say that is clearly understood.
Wait until after November. She's under the radar now supporting a GOP congress all over the place packing the venues. Patience is a virtue. And very few people trust the TV media regime.
